   4 Subject: [PATCH 165/247] media: atmel: atmel-isc: extract CBC submodule config
   5  into separate function
   6
   7 The CBC submodule is a part of the atmel-isc pipeline, and stands for
   8 Contrast Brightness Control. It is used to apply gains and offsets to the
   9 luma (Y) and chroma (U, V) components of the YUV elements.
  10 The CBC submodule should be initialized in the product specific driver
  11 as it's product specific. Other products can implement it differently
